Nicola Crane commented on ARROW-14544:
--------------------------------------
I had a bit of a check of this in R Internals
(https://cran.r-project.org/doc/manuals/r-devel/R-ints.html) and there's this
exerpt:
{code}
_R_CHECK_SUGGESTS_ONLY_ : If set to a true value, running examples, tests and
vignettes is done with a temporary library directory populated by all the
Depends/Imports/Suggests packages. (As exceptions, packages in a
‘VignetteBuilder’ field are always made available.) Default: false (but true
for CRAN submission checks: some of the regular checks use true and some use
false).
_R_CHECK_DEPENDS_ONLY_: As for _R_CHECK_SUGGESTS_ONLY_ but using only
Depends/Imports (and the exceptions, including test-suite managers in
‘Suggests’). Default: false
{code}
In addition, the description in the README linked to above says "tests on
x86_64 Linux with R-devel using _R_CHECK_DEPENDS_ONLY_=true, so packages in
Suggests (and Enhances) are not available, (other than recommended packages)."
My interpretation of this would be that it is just that flag that is required.
However, if you suspect anything more complicated than expected is going on (as
I know can be the case with these kinds of things), I'm happy to do a more
thorough job of setting this up manually anyway - let me know what you think
[~jonkeane].
